Actizyme
is an enzyme and bacteria mixture designed to digest sludge to maintain the
efficiency of the filter. At the same time it provides useful bacteria to
help boost the efficiency of the biological filter. Reduces nitrite levels
when the filter gets "stuck". Actizyme should be added to the filter
every week.
